I don't know what exactly happened, but my desktop on Windows 11 doesn't show the icons anymore. It only displays the Recycle bin and, for some reason, when it is selected the shaded region is now a horizontal line (this shaded region indicates icon selection and usually is just a square shaded region around the icon).

There are other icons of text files in my desktop, but they are not visible on the Desktop. Only when I go into explorer and see what's on the Desktop:

When I changed the relative positions of my two monitors in system settings, I see that the icons appear to be all sitting on top of each other. Even when I have only my notebook monitor, the problem persists.

Any ideas on how to fix this? When I switch to another Windows user, I don't have this problem.
